My customer has a Galaxy S5 that has run out of phone memory. The phone has 16G of RAM with about 400M free. The phone has a 60G SD card with about 30G of fee space so I want to move data (primarily pictures) from the phone to the SD card. I attempt to copy and past the pics but when I try to paste, the system locks up. The normal Windows copy/paste dialog box displays a message that the "phone" is busy and then it locks up. I have waited as long as 10 minutes and still nothing. I initially tried to copy all the pics but when it didn't work, tried to copy only 1 pic with the same result/response. I can view and browse all of the folders on the phone. This is a Samsung SM-G900V phone and I have Windows 10 on my laptop. I tried to copy and paste to a Mac and had the same issue.
